Very nice drill bits and case.

Needing some metric drill bits I found these on Amazon. Never heard of the company before but read all the comments on Amazon. Nothing but good.I now have the drill set and I am very impressed. Very heavy metal box, all drill bits measure in with my calipers.Also these bits drill very nice holes in both wood and aluminum.I am giving these guys 4 stars because I do not know how long they will stay sharp. If they do then 5 star will be a no brainer.The set consist of 22 drill bits in sizes that metric people need, ranging from 1mm. to 13mm.
